Sort posts by number of likes

[piotrkulpinski]

Hi guys,
I was wondering if you know any way to sort posts by the number of likes they have?
I know I can do that using 'orderby' => 'meta_value_num' but then it won't include the results that don't have the post meta value in the database.

Thanks!

I just integrated this with a site I did and needed to output the 3 most liked posts. I combed through the code a little and they are actually adding a meta value that can be queried.

Here is how I did it and it worked:

$args = array(
	'post_type' => 'post',
	'posts_per_page' => 3,
	'orderby'   => 'meta_value_num',
	'meta_key'  => '_user_liked',
);
